Rose plant named ‘POULdrik’

ABSTRACT

A new garden rose plant which has abundant, coral pink flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of garden rose plant which originated from a controlled crossing between MACrexy (U.S. Plant Pat. No. 6,713) and an unnamed seedling (non-patented). The two parents were crossed and the resulting seeds were planted in a controlled environment. The new variety is named ‘POULdrik’.

The new rose may be distinguished from its seed parent, MACrexy, by the following combination of characteristics:

1. The seed parent has over 40 petals per bloom, while ‘POULdrik’ has 14 to 18 petals;

2. The seed parent has light to medium pink flowers, while ‘POULdrik’ has coral pink flowers.

The new variety is similar phenotypically to the pollen parent, an unnamed seedling created by the same inventors, in that both varieties are floribundas with semi-double pink flowers.

The objective of the hybridization of this rose variety for garden use was to create a new and distinct variety with unique qualitites, such as:

1. Uniform and abundant coral pink flowers;

2. Vigorous, compact growth;

3. Cold hardiness and disease resistance.

This combination of qualities is not present in previously available commercial cultivars of this type and distinguish ‘POULdrik’ from all other varieties of which we are aware.

As part of their rose development program, L. Pernille Olesen and Mogens N. Olesen germinated the seeds from the aforementioned hybridization and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.

‘POULdrik’ was selected by the inventors in the spring of 1988 as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘POULdrik’ by traditional budding was first done by L. Pernille and Mogens N. Olesen in August, 1989. This initial and other subsequent propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULdrik’ are true to type and are transmitted from one generations to the next.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying color illustration shows as true as is reasonably possible to obtain in color photographs of this type, the typical characteristics of the buds, flowers, leaves, and stems of ‘POULdrik’. Specifically illustrated in SHEET 1:

1. Stem showing branching and the attachment of leaves, buds, and peduncles;

2. Flower bud, partially opened bud, and open bloom;

3. Flower petals, detached;

4. Sepals, receptacle, and pedicel;

5. Flowering stem as well as a bare stem exhibiting thorns;

6. Leaves.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘POULdrik’, as observed in its outdoor growth in a field nursery in Jackson County, Oregon. Observations were conducted during October, 1998, on an eighteen month old plant. Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 1995, except where common terms of color are used.

For a comparison, several physical characteristics of the rose variety ‘POULander’, a rose variety from the same inventors described and illustrated in U.S. Plant Pat. No. 6,265 and issued on Aug. 30, 1988 are compared to ‘POULdrik’ Chart 1.
